The Xuandu Copper City took root on the edge of the southern foot of the Heiyin Mountains, and it was already after the third day.

The sixteen towers are directly connected to the leylines, and the Qianzhang Copper City is like taking root among the mountains, and there are many forbidden level arrays inside, and the protective spirit shield envelops the jet-black stone ridges in a radius of more than ten miles outside the copper city.

In this way, the main forces of Longmen Sect, Xuandu Sect, Wushan, and Qingwangfu, more than 300,000 people and horses can move north from the northern foot of Zhouwu Mountain to Tongcheng, forming a direct attack on Heiyin Ridge.

The canyon where the spatial crack of the Thousand Demon Realm is located, the Yunzhou Sects call it the Evil Ghost Gorge, and it was previously the place where the Yin Evil in the Black Yin Ridge was the most dense and the ghosts were most concentrated.

The terrain of the Devil Gorge is extremely treacherous, and it is also because of this that the spatial wall is easy to distort here, and it is easy to form a relatively stable spatial crack after tearing the spatial wall.

From the Copper City to the Devil Gorge, there are still thousands of miles away.

Even if the Yin Demon Miasma in the sky above the Black Yin Ridge is difficult to exclude, floating warships such as the Golden Scale Boat and the Dragon Tooth Boat can continue to fly for more than 5,000 miles after the internal formation prohibits and absorbs enough spiritual energy.

The Yunzhou Sects have a firm foothold in the Copper City at the southern foot of the Black Yin Mountains, which means that the disciples of the Sects can directly advance from the Copper City to the Evil Ghost Gorge in a floating warship, and there is no need for any transit in between.

Once the battle in the Demon Gorge is lost, you can also retreat directly to the copper city to hold the defensive line.

The Demon Clan's choice to tear apart the spatial wall in the Demon Gorge was limited by the special terrain of the Black Yin Ridge, just as it was no accident that the location where the Heavenly Flame of Tu Mountain appeared was in the same Thousand Demon Sea as the mouth of the Demon Ruins.

Although the Demon Gorge is not in the extreme depths of the Black Yin Ridge, it is a place that the demons must defend, and they also hope to establish a relatively stable spatial channel on this basis, so that the hundreds of millions of demons in the Thousand Demon Realm can continue to pour into Yunzhou.

When the time comes, they will be able to expand from the Black Yin Ridge to the Zhou Wu Mountain in the south, and then swallow up the Northern Regions and the entire Yunzhou......

The demons are three or five hundred miles deep from the Evil Ghost Gorge to the south, and they choose the evil cave and yin veins to set up a demon array, and build a deep mountain stone wall, which is an obstacle that the disciples of the Yunzhou Sects can not bypass before advancing to the Evil Ghost Gorge.

And after the spatial crack in the Evil Ghost Gorge opened, a large number of demons poured into the Black Yin Ridge, making the evil array set up by the demons near the Evil Ghost Gorge extremely powerful.

No matter how difficult it was to attack, these obstacles must be removed, and the final plan was that the disciples of the main sects in the Northern Regions would advance to the Evil Ghost Gorge from the front with the Xuandu Sect; Wushan, Longmen Sect, and Qingwangfu would join forces and advance from the left flank; Chunling Jun personally supervised the reinforcements of the Lingtian Army, the Xuantian Sect, and the Xuanhuo Sect, the second largest sect in the Northern Regions, to advance to the Evil Ghost Gorge from the right flank.

In addition to the Xuandu Sect and the Xuanhuo Sect as the first and second largest sects in the Northern Regions, other large and small sects and clans in the Northern Regions also have a total of two or three hundred thousand disciples to reinforce Zhou Wushan, which is the main force of this battle.

The demon clan first came out from the depths of the Black Yin Ridge, mainly because of the temptation, and the demon soldiers and ghost soldiers who killed from the steep canyons and caves with the terrain were limited in scale, and they did not cause much resistance to the children of the sects who advanced to the edge of the Black Yin Ridge in the early stage, but after it was determined that the goal of the Yunzhou Sects in this battle was the Evil Ghost Gorge, a large number of demon soldiers and ghosts began to gather in the south of the Evil Ghost Mountains, and the intensity of the war was stronger day by day.

For the demon race, whose true spiritual wisdom is not inferior to that of the human race, he can naturally know in his heart that once all the sects of Yunzhou can mobilize and unite, the various magical means they possess are definitely not the demon clans that are not very good at formation prohibition, and they can defend against it by relying only on a few deep mountain barriers.

The advantage of the demons lies in the absolute number, and the numerical advantage of the demons cannot be exerted by trapping a few deep mountain barriers that are not large in scale.

It is often said that "millions of demons" are far from the Black Yin Mountains, but in fact, this refers to the number of high-level demons with spiritual intelligence.

In addition, in the Black Yin Mountains, the low-level demons who were controlled by the bloodthirsty killing will were actually more than ten times more than those of the high-level demons.

This is still the number after the low-level monsters were consumed in large quantities in the Thousand Demon Sand Sea and in the Old Dragon Pool.

In addition, there are still a large number of ghosts in the Black Yin Mountains, all of which are used by the demon clan at this time.

Under the influence of the Yin Demon Miasma, advancing into the depths of the Black Yin Ridge, the power of the Xuanlei Chariot was greatly restricted, and in the thunderclouds tumbling in front of the formation, the density of the electric snake thunder that could be gathered was reduced by more than half, but one after another thunder pillars were violently released from the thunderclouds, and they still tore open one after another from the dense torrent of demon soldiers and ghost soldiers.

However, there are too many demon soldiers and ghost pawns, and these torrents of low-level demon soldiers and ghost pawns are completely controlled by the will to kill, and the only way to stop them is to crush them to pieces.

No matter how majestic and majestic the true yuan mana in Chen Xun's body is, there is no way to block the rush of tens of thousands of demon soldiers and ghost pawns like a reef for a long time.

Ji Lie's cultivation of the True Body Law Phase, and the Spiritual Qi Gathering Golden Scale Sword from the Void is not limited by his own True Yuan Mana, but the Golden Scale Sword Law Aspect is also shattered when it is subjected to violent attacks.

Once the Golden Scale Sword Law was violently shattered, Ji Lie's own Yuan Shen was still traumatized, and in the direction that Ji Lie was responsible for, once there was a short-term vacancy, the pressure faced by the disciples of the four sects would multiply, resulting in great casualties.

Northern Xuanjia, Su Tang, Gu Chengzhuo, Jiang Bingyun and others, the Xuanbing Seal used for sacrifice is also limited, after withstanding the fierce attack, the divine soul aura attached to the Xuanbing Seal will be dispersed, if it is not retracted for sacrifice, the divine consciousness will completely lose control over the Xuanbing Seal.

The easiest thing is the Firewing Demon Ape.

The Firewing Demon Ape cultivated into the Golden Body of the Demon Ape, and the monsters below the level of the Little Demon General could not cause any damage to it at all. And it advances and retreats with the disciples of the four sects of Wushan, and is not afraid that its short handle will be used by the demons, and it is not afraid that it will fall into the encirclement of the demons and be difficult to get out, and it can give full play to its strongest attack power without any scruples.

It swung out with a red flint stick, like a fire cloud covering a range of more than 100 zhang, and ordinary demon soldiers and ghost pawns would be crushed and smashed if they touched this fire cloud.

No matter how strong the Fire Wing Demon Ape is, the area that it can control is also extremely narrow, and it can only ensure that the array of disciples of the four sects of Wushan is less than a hundred zhang wide, and it will not be directly attacked by the demon soldiers and ghost soldiers.

This battle cannot completely rely on a few Heavenly and Human Realm powerhouses to forcibly tear through the defenses of the demon clan and enter the Demon Gorge.

Not to mention that after several Heavenly and Human Realm powerhouses entered the Evil Ghost Gorge, they had to avoid interference as much as possible before they could cast spells to seal the spatial cracks; even if the Heavenly and Human Realm powerhouses were not afraid of the siege of low-level monsters, to be surrounded by dozens of heavenly demon generals and hundreds of small demon generals led by the Demon Marshal Chihuo Ming in the depths of the Black Yin Ridge, it would be a bleak ending for nine deaths.

After Chen Xun and the others entered the Heiyin Ridge five or six hundred miles deep, the resistance they encountered became extremely great, but they joined forces with the Longmen Sect and the Qingwang Mansion to advance from the left flank, and two days later, the Wushan Forward Array advanced to a stone ridge.

A large area of rolling dark black clouds shrouded most of the stone ridge, and there was a faint light and thunder floating between the black clouds, which was no different from the evil array seen in the Thousand Demon Sand Sea back then.

If there is a difference, it is that when there was a Thousand Demon Sand Sea, the demon clan could only set up one evil array, but I didn't expect that after decades, there were dozens of such evil arrays in the depths of the Black Yin Mountains.

Saying that the demons are not good at formation refining, that is only relative.

In addition to the evil array, the demon clan has also built a stable space channel between the Thousand Demon Sand Sea and the Thousand Demon Realm, which shows that the level of the demon clan's refining weapons and formations is far above Wushan.

It can only be said that the demon clan is slightly worse than Yunzhou in terms of formation refining weapons as a whole, and it cannot be compared with the Tianjun Realm.

Seeing that the demonic black clouds shrouded dozens of miles of stone ridges were closed, people didn't know how many monsters were hidden in the demon array, Chen Xun secretly felt that the demon clan's evil array here was not much worse than the human race's top ban-level mountain protection array.

The demons have long understood the benefits and disadvantages of the Blue Flame Lotus Arrow, and naturally they will never let the Wushan disciples approach the Evil Array lightly, so that the dense arrow array of the Blue Flame Lotus Arrow can directly destroy the Evil Array that they have worked so hard to deploy.

Among the elite archers who acted with the forward array in Wushan's battle, there were 800 disciples who had cultivated the Luo Yu Divine Bow Technique to the Initial Heavy Realm.

Although their attainments in the Luo Throat Divine Bow Technique are extremely shallow, far from being able to shoot distant objects one or two hundred miles away with one arrow like Tie Xinmei, who are powerhouses in the Yuan Dan Realm like Tie Xinmei, they have also increased the dense arrow array of the Blue Flame Lotus Arrows from the previous three miles to ten miles.

The shooting distance of the dense arrow array has been increased to ten miles, which means that these eight hundred elite archers can be firmly protected at the core of the forward array when they move with a golden-scaled ship.

Unless the forward array is completely destroyed by the demons, the dense arrow array of the Blue Flame Lotus Arrow will always be the sharpest and most powerful means for Wushan to kill the enemy and break the formation.

The core goal of the battle of the four sects of Wushan is to destroy the demon barrier in front of them, and then contain a part of the demon soldiers from the left flank, so as to ensure that the main forces of the northern regions led by the Xuandu Sect can advance to the Demon Gorge along the way.

The four sects of Wushan mobilized 3,000 disciples above the realm of rebirth this time, but the proportion of the alliance army of the various sects was still small, so it was naturally impossible to undertake the main task of this battle.

The body of the demon god that Chen Xun had transformed with the Heavenly Detention Demon Banner was already in tatters.

Even if the Heavenly Detention Demon Banner swallowed a large number of monster remnant souls these days, the replenishment could not withstand the consumption, and the main souls of the Demon Banner refined by the Rakshasa Demon and the Skeleton Demon Yuan God became weak.

Seeing that the core target of Wushan's battle was thirty or forty miles away, Chen Xun knew that it was time for them to use all their milk strength, so he opened his mouth and forced out a large amount of life essence blood, which was sprayed directly on the Dutian Detention Demon Banner.

Nourished by Chen Xun's purest life element essence blood, the main souls refined by the Rakshasa Demon and the Skeleton Demon Yuan God all rose up with fierce spirits and let out a roar that shook the heavens and the earth.

The broken body of the demon god revealed a fierce flame, and it also suddenly swelled, several points stronger than at its peak.

Chen Xun cried blood in his heart, the main soul of the Demon Banner was detained, and he fed it with the essence blood of the life element, and the effect was the best, but his cultivation was profound, and this mouthful of life essence blood would take him several years of hard cultivation to make up for it.

Seeing that Chen Xun was like this, Zhao Chengen, who was in charge of the battle flag in the forward array, reminded Gu Chengzhuo, Lei Wanhe, Su Tang and others at this time to use their strongest means.

Ji Lie Ren was torn apart by several skeleton demons, took out the Juyuan Spirit Bottle from his arms, swallowed a large mouthful of Yuan Liquid into his abdomen, and the purple flame and blue light flashed all over his body, as if the veins of a hundred bones were about to be broken by the true Yuan mana that was violently released, and then he flew to the front of the formation, and a spirit sword flew out of the storage bag he tied to his waist like a carp crossing the river, and soon formed a small thousand sword formation around him.

The small thousand sword array is also divided into nine realms, and if Ji Lie's cultivation time is short, he will only cultivate to the third realm, even so, the small thousand sword array composed of three hundred spirit swords, the power of slashing the enemy is already far more than the golden scale sword method and the sea divine power of sword qi attached to the Great Easy Sword Technique itself.

The Xiao Qian Sword Array and the Lei Yin Sword Array are in the same vein, and they are more powerful, but the same disadvantage is that it consumes a lot of their own True Yuan mana.

The Yuan liquid refined from Xianao Island solved the problem of insufficient true yuan mana.

In the past few years, Xianao Island has refined the yuan liquid, and it is only twenty catties, and Du Liangyong has brought it back to Wushan.

In addition to the five catties of yuan liquid given to Tao Jinghong, the remaining one was divided into five, Ji Lie three catties, Chang Xi three catties, and the Fire Wing Demon Ape three catties, Chen Xun and Zhao Chengen, Hu Taiyan, and Su Tang They were divided into three catties, and the last three catties were left in the Demon Killing Dao Palace to make a little reserve.

On such a critical occasion, it should be Ji Lie who unleashed his strongest attack power.

A majestic snow-colored brilliance rushed up from behind Ji Lie, and the three hundred spirit swords suddenly seemed to boil, and the snow-colored sword qi erupted like a snow-covered mountain, spreading forward with the speed of thunder.

The power of the Little Thousand Sword Array at a certain point may be less than the Sea of Sword Qi, but the range it covers is a hundred times that of the Sea of Sword Qi.

The monsters that were blocked in the range of six or seven miles in front of the forward array, dense stubble like a black tide, were all chopped into meat and bone residue by the sword qi of the snow-covered mountain in the blink of an eye, and there were only a dozen little demons left to stand on the spot, and they didn't know what happened all of a sudden.

The Little Thousand Sword Array was so powerful, the Firewing Demon Ape was taken aback, even if it destroyed the Red Lotus Flame Sea to the extreme at this time, it might not be able to have such an amazing power.

How powerful is Wushan's magic powers, why do you have to scare other people's jaws when you take it out?

The Firewing Demon Ape was itchy and hated in his heart, itching because Wushan had a powerful magical power worthy of its cultivation, and hating that he didn't know what he would do by being blackmailed by Chen Xun's bastard guy.

In the blink of an eye, the Little Thousand Sword Array swept out a passage approaching the Stone Ridge, and while the demons did not react, the forward array quickly moved forward.

Although Wushan has accumulated hundreds of thousands of Green Flame Lotus Arrows for decades, this kind of one-time consumable, no matter how much the reserves are, cannot withstand the huge consumption.

Previously, unless there was a danger that the forward array might collapse, it would concentrate on using the Blue Flame Lotus Arrow to block the attack of the demons.

At this time, he couldn't take care of the loss of the distressed Green Flame Lotus Arrow, and the dozen or so powerful monsters that the Xiao Qian Sword Array couldn't get rid of were all shot by hundreds of Green Flame Lotus Arrows intensively, ensuring that they were killed in the shortest possible time, so as to ensure that the rapid advancement of the entire forward array would not be disrupted.

In this way, the forward array of Wushan moved forward thirty miles in a short period of time, and directly advanced to the foot of Shiling Mountain.

At this time, a large number of monsters rushed out from the black cloud-like array on the top of the mountain, Zhao Chengen gave an order, and eight hundred elite archers shot the Blue Flame Lotus Arrows at the cliff in front of the forward array.

A large number of monsters poured out, and if the forward array wanted to get close to the range of four thousand zhang, it was very difficult and dangerous to directly attack the body of the evil array.

They couldn't figure out how many monsters were hidden in the dark clouds, and if they were too close to each other, they would be swept by a flood of monsters far beyond their imagination, and their situation would become extremely dangerous.

If you don't directly impact the body of the evil array, then destroy the stone ridge and destroy the evil acupoint yin veins deep in the underground of the stone ridge, and the effect will be the same.

The Yin Vein of the Evil Cave is destroyed, and the Evil Array placed on the Yin Vein of the Evil Cave will naturally lose its effect, and the monsters hidden in the Evil Array will naturally be exposed.

The sword qi of the small thousand sword array was like a snow-covered mountain, and it was difficult to gather the attack points in one point, forming a violent impact on the earth's rock formation that was thousands of zhang or even tens of thousands of zhang away, but the blue flame lotus arrow had such power when it fired a thousand arrows in a volley.

Thousands of cliffs collapsed like building blocks, and the stone ridges that stretched for hundreds of miles were shaking in the earthquake.

The Blue Flame Lotus Arrow fired a salvo of thousands of arrows, and the power displayed at this moment was no weaker than the most authentic Ground-shaking Dao Talisman.

In terms of convenience, the earth-shaking Dao talisman that can directly impact the spiritual vein rock layer deep underground is much more convenient and simple to use, but the Dao talisman is extremely difficult to refine, and it also consumes a large number of extremely precious materials, which is not available to any sect.

Although the Blue Flame Lotus Arrow needs to train a large number of elite archers, and needs to be protected in the core of the array when fighting the enemy, there is a lot of trouble, but the Blue Flame Lotus Arrow can not only impact the spiritual vein rock layer deep underground.

Waves of green flame lotus arrows shot out, and there were cliffs and gravel everywhere, Chen Xun and the others couldn't find out how deep the underground rock formations were destroyed for a while, but he, Ji Lie, Zhao Chengen, and Chang Xi could all sense the yin veins of the entire stone ridge, and the yin and evil demon miasma that could be gathered was weakening sharply.

The formation is difficult to break, and the source is cut off first.

At this time, Ji Lie and the Firewing Demon Ape both used a large amount of Yuan Liquid to replenish the consumption of True Yuan Mana, and they did not hesitate to destroy the Xiao Qian Sword Formation and the Red Lotus Flame Sea to the extreme, blocking a large number of monsters from the two wings;

Although the evil array on the top of the mountain was weakened, it was also activated at this time, and more than a dozen black-scaled giant claws poked out of the void and suddenly grabbed the forward formation.

The demon clan's evil array, the power should not be underestimated, more than a dozen black-scaled giant claws poked out of the void, just want to make a dozen law phase realm powerhouses shoot together, and the protective spirit shield of a single golden-scale ship can't support it, but there are already preparations in the forward array, Zhao Chengen's battle flag waved, and more than a hundred spirit swords came out of the formation, and immediately twisted half of the black-scaled giant claws into pieces.

Although half of the black-scaled giant claws passed through the sword net and turned into an incomparably violent black flame stream that flew down, it was not able to break the protective spirit shield of the golden-scaled ship.

Seeing this scene, Chen Xun was especially emotional.

Back then, in the Thousand Demon Sand Sea, in order to ensure that the arrow array was not defeated, in the face of the black flame flow sent out by the evil array, they could only use human lives to fill it.

"Boom!"

The Blue Flame Lotus Arrow fired another volley, and the cliff on the southern slope of Shiling was more than ten miles wide, and the entire collapse collapsed, and a corner of the evil array also collapsed directly.

The black clouds dispersed, and more than a dozen black-scaled giant claws that faintly poked out of the void suddenly turned into invisible, and the main ridge of the Stone Ridge, which stretched for hundreds of miles, was completely exposed, and the black pressure did not know how many demon soldiers and ghost soldiers had gathered.

Chen Xun saw that his scalp was numb, fortunately he didn't think about saving the Blue Flame Lotus Arrow, although it would not waste as much as thirty or forty thousand pieces of Green Flame Lotus Arrow if he approached the body of the Evil Array and then used the Green Flame Lotus Arrow, but at that time, so many demon soldiers and ghost soldiers hidden in the Evil Array rushed down the mountain together, how strong would the impact force be formed?

Not to mention those low-level monsters and ghosts, there are as many as seven heavenly demons and demon generals with a single body shape of more than seventy or eighty zhang.

Although Chen Xun and the others also expected that it would be impossible for the demon clan to deploy the main force on the left flank, they were also shocked to see that there were seven Heavenly Demon-level demon generals on the ridge and hundreds of little demon generals who had cultivated into Yuan Dan, which was a cut more than they had estimated.

In addition to the Rakshasa Demon and other heavenly demon-level demon generals that I had seen in the past, there were also four skeleton ghost generals with hideous faces, these skeleton ghosts were much shorter than the Rakshasa Demon, but the floating green flame light and the gloomy aura exuded were not slightly weaker than the Rakshasa Demon, and Chen Xun even had a more headache intuition.

Could these be the ghosts that the former Ji clan general turned into after he died in the Black Yin Ridge?

These demon generals and ghost generals obviously didn't think that Chen Xun would directly destroy the Evil Vein Rock Formation at any cost in order to achieve the goal of destroying the Evil Array.

The process is very complicated, but in fact, the time for twenty or thirty waves of Blue Flame Lotus Arrows to fire a salvo is extremely short.

After the ghostly clouds dissipated and the situation on the stone ridge was completely exposed, these demon-level demon generals and ghost generals came back to their senses and commanded hundreds of thousands of monsters and ghosts in the evil array to rush to the foot of the mountain together.

A line of snow swept from the far sky, and in an instant, it turned into goose feathers and covered the entire mountain.

Many monsters didn't know where the heavy snow came from suddenly, and they felt that the snow flakes were falling, like a thousand blades, rolling towards them, and their exposed scales and bones were all damaged unimaginably.

Heiyin Ridge is already an extremely cold place, and the slightly higher ridge ridges are all blown by the Xuan Han Gang, but the chill revealed by the snow flakes is a hundred times more violent than the Xuan Han Gang on the top of the highest peak of the Black Yin Ridge.

Thousands of low-level monsters were directly frozen into ice stones, rolled down the mountain, and shattered into a pile of ice slag when they collided with the cracked mountain rocks.

Tao Jinghong seemed to step out of the void, appearing in the mid-air in front of the Wushan forward array, and more than a dozen snow lines rolled out from behind him like a snow dragon, turning into goose feather snow, covering the southern slope of Shiling for dozens of miles.

"Tao Zhenjun shows his might, but we don't need to make a move!" Chen Xun laughed, he was still very nervous just now, but he didn't expect Tao Jinghong to come to help as soon as possible.

"We're going to break through the formation, and I don't see how many demons are guarding it, so I think of your side and the Shizi's side, there may be some problems. Tao Jinghong retreated into the forward array of Wushan, joined Chen Xun and Ji Lie, and talked about the battle situation of the Longmen Sect two hundred miles away.

Wushan, Longmen Sect, and Qingwangfu were responsible for outflanking from the left flank, and the battle line was stretched for six or seven hundred miles, and the black yin mountain was extremely dense with evil and demonic miasma, and the divine sense was greatly limited to detect anything.

The direction that the Dragon Gate Sect is responsible for can only be seen clearly after the Demon Formation is broken.

Moreover, Luo Yuze, Song Xuanyi and other disciples of the Longmen Sect, who were a little slower, also rushed over to join the Wushan Forward Array and kill the current demon clan.

Tao Jinghong alone, it is enough to reach half of the forward array of Wushan, just now this hand of Qianqiu Xue froze and killed tens of thousands of low-level monsters, the heavenly demon-level demon generals, ghost generals are not stupid, looking at the shape shì is not right, he is covered in the black flames of Xuanguang, and he flies in the direction of the Evil Ghost Gorge.
